Hertz HEX65MWO 6.5" Marine Coaxial 50W RMS IP65 White Grille Certified

Hertz 6.5" Marine Coaxial Speaker 50W RMS / 100W Peak, IP65, ASTM UV & Salt Fog Certified, White Grille, Twist-Lock, Neodymium Tweeter, Resettable Protection.

Product Overview

The Hertz HEX 6.5 M-W-O is a 6.5" marine coaxial speaker bearing the Hertz Pure Marine certification tested and verified to IP65 (total protection against water jets), ASTM-D4329 UV resistance, and ASTM-B117 salt fog standards. Designed for boats and marine environments where standard automotive speakers fail, the HEX 6.5 M-W-O combines marine-grade materials and construction with refined acoustic engineering.

The high-efficiency tweeter is FEM-simulation optimised for maximum off-axis dispersion critical for in-boat listening where listeners are rarely positioned directly on-axis. The woofer features a 25mm voice coil fine-tuned for infinite baffle applications with silicone-insulated lead wires for durability. A sealed built-in crossover with resettable solid-state tweeter protection, nickel-plated corrosion-resistant terminals, and a sound-transparent mesh grille with twist-and-lock system complete the package. The Marine Total White grille finish integrates cleanly into any boat interior or deck aesthetic.

Mounting depth is 85mm (3.25") with a 172mm outer diameter suitable for installations where depth is limited.
